### Creating a Measured Line

Measured Line button

With the Line button, you can measure the orientation and linearity of a line that belongs to a plane aligned with a reference plane or a line in space. To create a measured line, you must take two hits on the part.

Measured Lines and Workplanes

When PC-DMIS creates a measured line, it expects the hits for the line to be taken at a vector perpendicular to the current workplane.

If your current workplane is ZPLUS (with a vector 0,0,1), and you have a block-like part, the hits for the measured line must be on a vertical wall of that part, such as the front or side.
If you then wanted to measure a line feature on the top surface of the part, you would need to switch the workplane to XPLUS, XMINUS, YPLUS, or YMINUS, depending on the direction of the line.
